Answer:

The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

Answer:

f(x) = (x+5)(x-4)

Step-by-step explanation:

Key skills used in this problem: Quadratic equations, factoring

1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)

2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.

3) The two factors would be 5 and -4.

4) So it would be (x + 5)(x - 4) when factored

Hope you understood and have a nice day!! :D

Answer:

f(x)= (x+5)(x-4)

Step-by-step explanation:

First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.

Answer:

We reject H₀ , we found enough evidence to support the claim

Step-by-step explanation:

Sample size   n = 1300

Sample  proportion  p  = 45 %     p  = 0,45   and   q  = 0,55

Proportion of population     p₀   =  42 %    p₀  = 0,42

Hypothesis Test                

Null Hypothesis                            H₀          p  =  0,42

Alternative Hypothesis                Hₐ          P   >  0,42      

A one-tail test to the right is needed to evaluate the claim

Sample size big enough to consider binomial distribution can approximate to normal distribution

1300*p > 10   1300*q > 10

Significance level   α  = 0,02    

z(c) fom  z-table is   z(c) =  2,05

To compute

z(s)  =  ( p  -  p₀ )  /√ (p*q)/n

z(s)  = ( 0,45 - 0,42 ) /√ (0,45*0,55)1300

z(s)  =  0,03 / 0,014

z(s)  =  2,14

Comparing   z(c)  and  z(s)     z(s) > z(c) then  z(s) s in the rejection region we must reject H₀  we found enough evidence to spport the claim

Given that,

Cost of 6 pounds apples = $4.00

To find,

Unit rate.

Solution,

We have,

6 pounds apples = $4.00

We can find the cost of 1 pound of apples as follows :

1 pound apples =$ (4/6)

= $0.67

So, the cost of 1 pound apples is $0.67.

Answer:

From the given figure we can see that :---

MN||PO, MN=PO and MP=NO

Therefore, angle M=angle N (adjacent sides of the trapezoid)

[tex](8x - 16) = (6x + 20) \\ 2x = 36 \\ \boxed{x = 18}[/tex]

angle M=angle N= (6×18)+20=108+20 =128°

angle O =(180°-128°)=52°

Answer:

60

Step-by-step explanation:

180-(100+20)=x

Answer:

-5 through 10

Step-by-step explanation:

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

(-8, 6)

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is:

y = -4 + 38

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

We have given that,

An equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1

(-8, 6)

y=mx+b

Where m is the slope

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is y = -4 + 38.

Step-by-step explanation:

Because 1 in 5 throws she get 1 in

Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.

And your answer is 2 out of 10 tosses.

Answer: [tex]\frac{20}{3} %[/tex]%

Step-by-step explanation:

Convert 3m to cm:

[tex](3m)(\frac{100cm}{1m} )=300cm[/tex]

Now divide 20cm by 300cm:

20cm/300cm=1/15

Multiply (1/15) by 100% to convert the fraction to a decimal:

(1/15)(100%)=[tex]\frac{20}{3} %[/tex]%

Answer:7c +6d +12

Step-by-step explanation:3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?​

                                       3c + 4c  +12d - 6d +7 +5

                                       = 7c +6d +12

You combine like terms which are 3c and 4c which gives you 7c .Next you combine 12d and 6d but this time u need to subtract since it has subtact sign in between 12d and 6d which gives you 6d.After that you combine 7 and 5 which u get 12 .Lastly you put all of the tersm together which are 7c and 6d and 12 which get you 7c +6d +12  as your equivalent expression.

Answer:

[tex]k = 8.35[/tex]

Step-by-step explanation:

Given

[tex]Gallons = 4[/tex]

[tex]Weight = 33.4lb[/tex]

Required

Determine the constant of variation (k)

This is calculated by dividing the weight of gallons by the number of gallon.

[tex]k = \frac{Weight}{Gallons}[/tex]

Substitute values for Gallons and Weight

[tex]k = \frac{33.4}{4}[/tex]

[tex]k = 8.35[/tex]

This means that 1 gallon weighs 8.35lb
